What Does C1960 Mean?
The ABS/stability control module has detected a fault in the driver brake apply circuit — this is the signal that indicates the driver is pressing the brake pedal. This circuit may be separate from the brake light switch and is specifically used by the ABS module for brake-assist, ESC intervention timing, and automatic brake hold features. The module cannot reliably detect driver braking intent, which degrades safety system performance.
Common Causes
30%
Faulty brake pedal apply sensor or brake pedal travel sensor
25%
Brake apply switch circuit wiring fault (open, short, or high resistance)
20%
Brake pressure sensor providing conflicting data with the pedal switch (correlation fault)
15%
ABS module input circuit fault on the brake apply signal pin
10%
Brake pedal mechanism binding, preventing the sensor from detecting full pedal travel
Diagnostic Steps
1
Monitor the brake apply PID and the brake pressure sensor PID simultaneously in live data. Press and release the brake pedal. Both should respond together — if one shows brake application and the other does not, the non-responding circuit is at fault.
2
Locate the brake apply sensor at the brake pedal. This may be a separate sensor from the brake light switch. Check its connector for secure attachment and measure the supply voltage and ground.
3
With the sensor connected, backprobe the signal wire while pressing and releasing the brake pedal. The voltage should change distinctly. Note the transition point and compare to the service manual specification.
4
If the sensor signal is correct at the sensor connector but the module reports a fault, check wiring continuity from the sensor to the ABS module. Look for damaged wires near the firewall pass-through and under the dash area.
5
Check the brake pedal mechanism for binding or restricted travel. The pedal should move smoothly through its full range. A stiff or sticky pedal can prevent the sensor from reaching its activation threshold.

The most common cause of C1960 (Driver Brake Apply Circuit Fault) is: Faulty brake pedal apply sensor or brake pedal travel sensor
Typical repair costs for C1960 range from $50 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Basic hydraulic braking still works, but brake-assist, automatic brake hold, and some ESC intervention features may be degraded or disabled. In emergency braking, the system may not provide maximum brake-assist force, requiring more pedal effort from the driver. Repair within a reasonable timeframe.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1960 to identify the root cause.
